Glossary Home Poetic Forms

Closed Form

The term “closed form” in literature refers to poems that use a closed, specific structure or pattern. This includes poems written in the form of a sonnet, villanelle, haiku, limerick, and more.

Closed form is a rarely used term that refers to structures in poetry. If an author writes a poem that conforms to a pre-specified structure, then they are writing in closed form. It is contrasted to open form, or free verse, in which the poet is not restrained by any predetermined set of rules.

The poem is four stanzas as long, and each of these stanzas maintains a structure of five lines, making them quintains. The poet also uses a consistent rhyme scheme of ABABA throughout. Here is an example: 

Because of the silent snow, we are all hushed

Into awe.

No sound of guns, nor overhead no rushed

Vibration to draw

Our attention out of the void wherein we are crushed.

The words “hushed,” “rushed,” and “crushed” rhyme in this closed form poem, as do “awe” and “draw.”

From field and thicket as the year goes by;

This famous closed form poem is also one of the poet’s best-known and most commonly studied. It details a harrowing night in the speaker’s life that includes incessant knocking and a talking raven that only says one word–“Nevermore.” 

Throughout, Poe used six-line stanzas, known as the sestets. In total, there are eighteen. The poet also used a consistent rhyme scheme following the pattern of ABCBBB and the metrical pattern trochaic octameter. Here is the first stanza as an example: 

Once upon a midnight dreary, while I pondered, weak and weary,

Over many a quaint and curious volume of forgotten lore—

    While I nodded, nearly napping, suddenly there came a tapping,

As of some one gently rapping, rapping at my chamber door.

“’Tis some visitor,” I muttered, “tapping at my chamber door—

            Only this and nothing more.”

Closed Form vs. Open Form

As noted above, closed form poems are written with a specific structure in mind. This could be a study rhyme scheme of ABABA or a meter maintained as fluidly as possible throughout the piece, like iambic pentameter

In fact, an open forum poem lacks a specified structure altogether. For example, some lines might only contain two or three words, while others stretch to ten or more. The poet might choose to use a few examples of rhyme but will not fully structure their poem with a pattern.
